The function of the shank is to guide and self-centre NUTFIX™ in the metal sheet. The groove located on the shank (for FE, FP and PE type NUTFIX™) retains the material of the workpiece, which flows under the pressure exerted during installation. The groove provides anchorage - and therefore the push-out force - of NUTFIX™. The knurling guarantees torque resistance.

FE type
Shank in metric dimensions. Profile suitable for applications on metal sheet thicknesses ≥ 0.6 mm. This design is the guarantee of very high mechanical resistance; tensile force, push-out force and torque.
Suitable for crimping in highly strain-hardened material.

PE type
Mechanical characteristics identical to the FE type. The flush side is reversed, in comparison with the FE and FP types.

PC type
The PC nut can be completely buried in the thickness of the workpiece where the application necessitates a flush finish on both sides (for metal sheet ≥ 1.5 mm thickness). It is more resistant than a simple thread of the metal sheet, and can be installed prior to bending of this last.
High mechanical resistance.

RE type
The principle of anchoring by squeezing enables installation on soft materials (composites, plastics, etc.).
NUTFIX RE also allows the assembly of two sheets by riveting.
